I recently went on holiday and me and my partner had unprotected sex one right after quite a bit to drink , a few hours later i started to get a bit of a stomach cramp so went to the toilet and i had a very light bleed . Since that night just over 2 weeks ago i have had a few unusual symptoms which make me think could i be pregnant ? I've had light cramps , been more tired than usual , hot and cold flushes, going to the toilet more than usual , more discharge than normal . I have taken 2 pregnancy tests both clear blue and both have been negative . I have started a very light period today which is alot lighter than i normally get . Is there any chance i could be pregnant despite the 2 tests being negative did i perhaps take them too early ?
